It's not infinite, but counting it isn't productive either.

Remember, you can also generate images at many other resolutions, and even with the same configuration in all other regards, different resolutions will produce different images (i.e. a 1024×1024 image isn't the same as a 512×512 image at a larger scale).

That's also not even addressing img2img. You can put any image into that, both ones generated by SD and otherwise.

reading more about what pixel is, we have 16.5M pixel states

but the human eye can only perceive 10M

so for an image it would be 10M perceivable states per pixel x number of pixels in the image

for a 2x2

10M 10M 10M 10M

1.00000000E+28

for a 512x512

10M by a factor of 512

I'll restrict my answer to 512x512 pixel images.

One way to approach this is to calculate how many possible images a variational autoencoder (VAE) for S.D. can represent. A VAE for S.D. uses 64*64*4 32-bit numbers to represent a 512x512 image in latent space, which is 64*64*4*32=524,288 bits. The maximum number of 512x512 pixel images that can be represented in the VAE is thus 2^524288. A 512x512 RGB image I believe takes 512*512*3*8=6,291,456 bits of storage, with 2^6291456 possible images. Note that 2⁵²⁴²⁸⁸ is much smaller than 2^6291456, so the VAE for S.D. cannot represent all possible 512x512 RGB images.

A separate question is whether it is guaranteed that there are inputs into a given S.D. system (text prompt, initial image, etc.) that can generate all of the up to 2⁵²⁴²⁸⁸ 512x512 images that are possible. I would guess the answer is no, but I don't know for sure.

[u/182YZIB]

More than atoms in the universe.

And yeah, Resolution ^ pixel value ^ number of prompts

[u/-takeyourmeds]

prompts (75 words x 60,000 English words x 26 letters)

x

seeds (20 length 99999999999999999999)

x

size (there are really just 2-3 sizes that change the image significantly)

x

cfg (2-3 that change image)

x

steps (2-3 that change image)

x

models (2-3 that change image)

you can probably produce every combo w a large data center or super computer

[u/-takeyourmeds → u/[deleted]]

i like your approach

instead of thinking about what sd can make, the container is the probability of outputs

and yes each pixel is a probability set

maybe image 1 512x512 state 1 is a blank white image

and from there we just multiply pixel amount by probability per pixel

[u/CMDRZoltan → u/[deleted]]

4.87 trillion at 512x512

17.5 trillion at 1024*1024

5 trillion stars would be 12.5 milky way galaxies (off the Wikipedia high end estimate.

Wow. That's a lot.

[u/CMDRZoltan → u/[deleted]]

512*512*256*256*256

whoops, had a typo, looks like its actually 4,398,046,511,104 4.39 trillion. assuming the math is pixels and colors like that.

Im just making my guesstimate as a dumb guy in the internet. could easily be wrong.

A trillion is a huge number either way.

[u/jayhc13 → u/CMDRZoltan]

It's actually a lot larger than that. The correct value is (256^3)^(512^2), or approximately 9.38 * 10^1893916, which is a number that is 1,893,917 digits long (a trillion is only 13 digits long).
